Muslims worldwide celebrate the start of Ramadan with fasting and service.

Muslims around the world have begun observing Ramadan, the month of fasting, self-reflection, and religious pursuits. Almost 2 billion Muslims will abstain from food, drink, smoking, gossip, and sexual relations during daylight hours. Ramadan is the holiest month for Muslims, and it culminates with the festival of Eid al-Fitr. Muslims in different parts of the world will have varying fasting hours, with some lasting up to 17 hours. World leaders, including President Biden, have wished Muslims a happy Ramadan. Cities across the world mark the month in a variety of ways, with some offering discounts and fireworks, while others warn of rising costs and greater need for charity aid.
